GTX1060 not working, Vcore down to 0.3V

well, I do not want to argue with you but from the 9511 datasheet, it is mentioned that it is a PWM signal, not serial.

It could well be PWM in the case of your controller IC - I was just generalizing

Hello Steptech,

Did you managed to solve this issue?

Currently I'm facing some kind of similar issue with my GTX 1070.
GPU works, but after I put some load (for example benchmark) card immediately goes off. I found that Vcore is missing and following voltages.

Currently what I have checked is that:
1. Vref=2V after crash;
2. En=2.4V after crash;
3. 5VCC=5V after crash.

So these are not the issue.

However what I have found that COMP goes from 2.2V to 0V after card crashes. And of course when COMP goes down, FB is also 0. Only EAP still has voltage. So from my point of view, when COMP/FB goes down UVP turns on (VFb<0.5xVeap solves equation).
